Hi, The ECal always has a 20 mm gap on top and bottom prior to the December commissioning run. The survey in December of the position of the ECal indicated that the top half gap is at ~23mm while the bottom half has a gap of 20 mm. We are still waiting to see the result from the most recent survey done this past week, but it is not expected to be significantly different. -Holly On Fri, Mar 6, 2015 at 1:46 PM, Graf, Norman A. <[log in to unmask]> wrote: > Hello All, > Can someone from the ECal comment on what the geometry should be? > HPS-Proposal2014-v9-2pt2 has a symmetric layout of the top and bottom > beamgap of 20mm > > <detector id="13" name="Ecal" type="HPSEcal3" > insideTrackingVolume="false" readout="EcalHits" vis="ECALVis"> > <comment>The crystal ECal</comment> > <material name="LeadTungstate" /> > <dimensions x1="ecal_front" y1="ecal_front" x2="ecal_back" > y2="ecal_back" z="ecal_z" /> > <layout beamgap="20.0*mm" nx="46" ny="5" dface="ecal_dface"> > <remove ixmin="-10" ixmax="-2" iymin="-1" iymax="1" /> > <top dx="ecal_dface*tan(beam_angle)" dy="0." dz="0."/> > <bottom dx="ecal_dface*tan(beam_angle)" dy="0." dz="0."/> > </layout> > </detector> > > Whereas HPS-ECalCommissioning-v2 has 20mm on the bottom and 23mm on the top > > <detector id="13" name="Ecal" type="HPSEcal3" > insideTrackingVolume="false" readout="EcalHits" vis="ECALVis"> > <comment>The crystal ECal</comment> > <material name="LeadTungstate" /> > <dimensions x1="ecal_front" y1="ecal_front" x2="ecal_back" > y2="ecal_back" z="ecal_z" /> > <layout beamgapBottom="20.0*mm" beamgapTop="23.0*mm" nx="46" > ny="5" dface="ecal_dface"> > <remove ixmin="-10" ixmax="-2" iymin="-1" iymax="1" /> > <top dx="ecal_dface*tan(beam_angle)" dy="0." dz="0."/> > <bottom dx="ecal_dface*tan(beam_angle)" dy="0." dz="0."/> > </layout> > </detector> > > > Thanks, > Norman > > From: Hansson Adrian, Per Ola > Sent: Thursday, March 05, 2015 4:04 PM > To: Graf, Norman A. > Cc: hps-software > Subject: Re: New geometry release > > Hi Norman, > > I don't know.
